WebApr 5, 2016 · The two main types of aluminum-carbon metallic composites – aluminum-graphene and aluminum-graphite – have been synthesized. Aluminum-carbon composites produced by the proposed method are compact and non-porous, with a characteristic metallic shine ( Fig. 1) and good electrical conductivity. WebGraphite is amongst the most commonly known and naturally found allotropes of carbon. It is comprised of a layered structure having sp 2 hybridized carbon atoms with one free electron capable of forming coplanar and interplanar bonding. The layers, stacked through secondary bond forces, can slide over one another [14].In other words, graphite …
